I am stumped. This doesn't look like the kind of browning associated with lack of moisture, and from what you've told me, the amount of shade the ferns are receiving hasn't changed. The regularity of the brown edges makes me think something happened to the fiddleheads before they unfurled (frost damage, maybe?), but that is just my guess.
I have emailed someone I know who grows ferns to see if he knows what's going on or can point me in the direction of a fern specialist who can diagnose this issue. I will get back to you when I find out more.
Fern specialist Jordan Metzgar of Virginia Tech conferred with a colleague who works in plant diseases, and they believe either a late frost or a dry spell was the culprit. They said you can just cut out the affected fronds. Fortunately there appears to be no long-term damage!
